The translator map seems to work with paletted colour values too, and the result is not clamped. Colours are passed to the GPU as unsigned bytes to multiplying by 16 will overflow, so we do the logic in the shader. If we passed floats we could skip the shader logic.

When the translator map is enabled the colour values seem to use 4 bits, 0-16. Why not 0-31 I don't know. Anyway virtua on is overflowing these values for some of the smoke effects. For us the numbers were wrapping around. Clamping is enough to fix this. (Thanks model123)

Sutherland-Hodgeman clipping only works for planar primitives. Scud is rendering non planar quads and this breaks our algorithm a little when using the quad renderer. Stretching the near plane a few % is enough to fix it.

Fix the sky in harley in first person mode where pixels in the sky are culled when they shouldn't be with the quad renderer. Basically we were running out of precision in a rare corner case. Doing the maths with double precision and casting back to float was enough to fix the issue.

To calculate the mipmap value the opengl needs to calculate the difference in the texture coordinates between adjacent pixels. If there are no adjacent pixels the hw may need to spawn invisible fragments outside of the visible polygon. Our algorithm was culling these out so the mipamp calculation failed for edge pixels. Anyway this fixes quad rendering looking broken with the latest nvidia drivers.

Thanks to our anonymous contributor who managed to patch a model 3 game and run it on real h/w, we were able to obtain some timing values we had been long been missing for correct emulation. The h/w polls something called the ping_pong bit at start-up to sync the GPU with the CPU. Unfortunately we didn't have the correct values and just manually used some per game hacks to get games to run. This mostly worked, but some games were writing more or less frames than they should have been for a given time period. When the ping_pong bit flips at 66% of the frame time, games were writing data for a new frame, which meant writes were often straddling 2 separate frames. We aren't 100% sure if IRQ2 or the ping_pong bit is vblank.

Ocean hunter in the middle of the game is passing a few matrices with FLT_MAX inside them, which blows apart our near/far calculation. The hardware must have some method to sanitize the near/far for instance if you render something extremely close to the origin you will also blow apart any near/far calc.

Technically backface culling should cull polys when the dot product = 0, since when it equals 0 the polys is perpendicular to the camera and thus invisible. When you complete sega rally2 (if you can get that far lol) the champagne is invisible. The reason is because all the face normals are 0. So when multiplied by the model matrix they are still 0 and get culled. Tweaking the condition to only cull polys when greater than 0 fixes this, and allows these 'bad' polys to render as they do on the model3.

Sega bass fishing is starting some off the meshes with a shared vertex. Without having a previous vertex to share with, the values were just uninitialised and junk. The hardware itself seems to hold the value from the previous mesh, and sega bass fishing relies on this undefined behaviour to function correctly. Storing the cached vertices as member variables instead of locally to the function means it holds the values from the last mesh, and uses those values instead of random garbage.

Draw transparent polys to separate layers and composite at the end. This solves a tonne of transparency errors we had been battling with for a long time. The model3 is strange in the fact it only supports a max of two translucent overlapped polys. They are not blended into the frame normally. Doing this means the topmost translucent polys only are visible in the scene, the equivalent of doing a depth pass first, but without the added cost.

The vertex shader is run before clipping is done. If fogging values are calculated and clamped in the vertex shader it can interpolate bad values, since the range has been truncated.

Star wars is the only game to pass unsigned fixed shaded values (per vertex brightness) to the renderer. Originally we thought that the specular flag would turn on unsigned values since it's the only game to set specular with these polys, but this logic turned out to be incorrect. The JTAG interface seems to config the GPU to turn on this functionality. (Harry Tuttle)

Fix the sky in one of the levels in virtua on. The problem was caused by the fact we didn't split the mesh by the fog % burn through, so all the polys had the same value. We could use a vertex attrib, but % burn through fog is so rarely used and when it is, normally every poly in the mesh has the same value.

Calculating the length of the vertex results in quite broken values for fogging when the vertices are traversing the view frustum. The hardware also wouldn't have been doing a square root per vertex for fogging. Simply using the z values is enough. Todo check clamping of values for the near/far planes.

Modern hardware does backface culling in window space by calculating the face normal for the polygon, then doing a dot product against the view vector. The real3d pro-1000 on the other hand passes a pre-calculated face normal for each polygon which is used for culling. We were using this face normal to rewind the polygons so that regular backface culling would work. This worked 99.9% of the time. However this was failing on some models in Virtua Striker. The reason was because the pre-calculated face normals being passed were actually completely different to the actual face normals for the poly (not just inverted like you would expect). This broke our code. The solution was to emulate face culling directly in the vertex shader using the pre-calculated face normals directly. Only minimally tested this but hopefully there are no obvious regressions.

Harry made some important discoveries with regards to fixed shading on the model 3 (per vertex poly brightness values). Firstly values are allowed to be negative, and they are used as a drop in replacement in the standard lighting equation for the normal dot light vector. This quite radically changes the brightness in LA Machine guns, but now correctly matches the arcade.

Finish fixed shading for 2.0 hardware. I'm pretty sure it actually works identically to step 1.5 hardware. The oddball is LA machine guns where the viewport ambient doesn't seem to effect the brightness. But the ambient works differently in this game because it uses the unclamped light model. Still need to investigate if the diffuse factor effects fixed shading.

Sometime ago I managed to work out that specular on the model3 is not real specular, and really is just an extension of diffuse lighting. But attempts were derailed by corner cases and the fact we were not handling the normals correctly. Anyway Harry managed to successfully come up with an algorithm, and coefficients that give an almost perfect match to specular on the model3, based soley on observations from video footage! He also worked out that the lighting on hardware 1.5 onwards appears to be unclamped (ie greater than 1). This quite radically changes the brightness of some of the games, but much better matches the original hardware.

Ski champ for some reason is passing denormalised numbers for the modelscale. This is causing a NaN in our shader killing the lighting for these models, so we simply skip these, since they are essentially zero anyway. Thanks to Harry for finding this bug :)

We were force normalising the result of matrix * normal, which looked correct in most cases. But this didn't preserve the scaling of the matrix, or the scaling of the model normals which resulted in many over bright areas. On it's own this generally worked, but games like Star Wars looked quite broken. Harry correctly figured out if you scale these normals by the scaling value that is sometimes present in the culling nodes the lighting looks correct. Still more work to do to correctly figure out the model3's lighting model.

Clamp the ambient light to a max of 0.75. LA Machine guns seems to use an ambient value of 1, which is full bright for everything. But for some reason the hardware seems to treat this as ~ 0.75. This fixes various missing shading in the game. This doesn't seem to have any negative effects on other games I have tested. Clamping in the shader as we might need the full range of values for fixed shading.

A second go at fixing the fixed lighting in star wars .. Fixed shading is per vertex poly colours. For some reason in star wars they are treated as unsigned values instead of signed, like in every other game. These polys are all marked with specular enabled, where as in the rest of the games they are missing this flag. That's the only difference I can find.

The real3d has a flag that allows the hw to skip polygons so that they aren't rendered. Sega rally2 uses this for the dust effects. Triangles or quads that have this flag are junk, and look like random corruption if you try to draw them. We assumed polys that shared vertices with these bad polygons were also bad. It turns out the last few shared vertices in these polys were in fact valid, and thus the entire quad/triangle strip should be drawn and not discarded.
